The basic principles used in Keyline of increasing the fertility of soils has not changed since they were first described in P.A Yeomans' book The Keyline Plan published in 1954. What has changed is the design of the cultivating equipments and the modification of the techniques for soil building that the newer designs have permitted. You can now make soil, much faster.

FIRST REQUIREMENT: We take the accumulated carbon dioxide out of the air by increasing the humus content of our agricultural soils.
To get the information on --- HOW THEY SELL THE IDEA THAT NUCLEAR IS DANGERIOUS, AND SOME OF THE FICTIONS THE SPIN DOCTORS DREAM UP
WE HAVE DOUBLE GLAZED HALF THE PLANET.
The carbon dioxide in the atmosphere produces a greenhouse effect. So effectively, for the last million years at least our Earth has had a sheet of glass covering us and keeping things nice and comfortable, and the weather systems STABLE.
Reducing emissions is a big joke. It's just slowing the rate we double glaze the other half of the planet.
So first; we have to remove the current excess; and second we stop putting more back in.
Removing it can only be achieved by soaking it into our agricultural soils by increasing the humus content of those soils. It's called soil carbon sequestration. It's explained below. Nothing else will work.
Stopping the adding can only be achieved by a complete change to renewable fuels. For power that's mainly nuclear energy and for transport it's got to be biofuels.
The geocarbon fuel industries have to go out of business.
Or just give up. And if you're over fifty, who cares?.
So many people ask about soil. They want to understand and say -----
Tell me in a nut shell.
How does soil carbon sequestration work?
How do you take the carbon dioxide out of the air
Allan Yeomans gives this answers---::
" Happily it's a completely natural process, but let's keep it simple.
1 Cows eat grass.
2 One bite, and the grass plant immediately sheds a few roots.
3 The cows produce waste.
4 Soil microbes and earth worms eat dead grass roots and cow's waste,
5 Grasses grow best in humus rich soil. So it's full circle, back to the cow.
That's why the most fertile soils in the world are the grasslands of the world, the steppes, the savannahs, and the prairies. And every one of those grasslands had some type of grazing animal living on it; often for a million years or more. Thus grassland ecosystems automatically create their own humus rich, hugely fertile top soils. It doesn't happen in forests so forest soils always slowly self-destruct.
Hard rock, near the surface, weathers down and becomes “subsoil”. Subsoil is biologically inert. But when humus is created in that subsoil, then it becomes “topsoil”. It's a billion year old process.
The chemistry is straight forward. Both living plant materials and soil humus are about half carbon. Carbon dioxide in the air is about one third carbon. Using carbon dioxide from the air, water from the ground, and sunlight from space, the chlorophyll in a blade of grass, or any other green leaf, manufactures living plant materials.
Herbivores eat grass, carnivores eat herbivores.
And we're omnivores; so we can eat both. "
This links to the explanation on where the concept of soil carbon sequestration originated. The origonsl paper was also entitled "Agricultural Solution to the Greenhouse Effectt "
THE SOIL CARBON SOLUTION ( the only chance we have)
(Added the below today Jan 30 2012. The links noted in the text are fairly standard stuff)
A 2009 study by the California Energy Commission concluded that the use of Keyline plows created the lowest carbon emissions from the subsoil and the addition of compost to grazing lands enhanced the carbon sequestration. This is an important finding because carbon sequestration, or the capture and removal of carbon dioxide from the atmosphere, is one of the methods to reduce carbon footprints and also a long-term solution to combat the accumulation of greenhouse gasses and global warming.
Regardless of the specific brand of plow used, the concept of the Yeoman's Plow and vertical tillage is a significant aspect of sustainable agriculture Keyline design, and holistic range management
